Yes I know exactly what you mean haha, but it gets really bad from March on, we were there in February, so still not that much sargassum 😉 And on the other hand we got to see the ligh effects of it at night which was truely awesome! Where do you guys live? if its not that far its definitely worth it to explore more at the Riviera! I will write about other cool places soon so stay tuned hehe!
Isla Mujeres used to be really reaaally beautiful back in the time! Now it is way too touristy for my taste - sadly. Except if you do the whaleshark tour and then chill right in front of it for the after chill 😉
